OK, that's made progress. Now I'm getting rename and move happening. But, a couple of problems still:
1. it's still not applying the {hd} tag - no resolution flag being set in the new name
2. I download two versions of each show. 1 in SD and 1 in UHD. What's happening is that the UHD version is being renamed and moved into the output folder (but without the UHD tag) while the SD version is being deleted. Is this because f the hardlink or copy option? Is there a different option so I can have both?

Did you install MediaInfo? After installing MediaInfo, did this message change?

2.
If {hd}{resolution} and friends work, then unique files will get unique file paths, so there won't be a conflict. That being said you can change what happens on conflict by changing the conflict option, e.g. you can make it add a number to avoid file name conflicts.

ok, well I'll have to see when more files get downloaded. FB is now not seeing anything to rename as I imagine it adds things to the excludes list once they have been processed?
Fingers crossed.
thanks
